For your consideration, a used Diamondback Platinum Shielded Power Cable for sale. Extra from an 'abandoned project'. Will post photos later.

ALPHA CRYOGENIC PROCESSAll internal wiring, connectors and conductive elements are treated with Shunyata Research's exclusive performance enhancing Alpha Cryogenic process.SHUNYATA RESEARCH'S ON-SITE CRYOGENICS LAB AND PROPRIETARY ALPHA CRYO PROCESSA normal cryogenic process consists of the treated materials being lowered to an extremely low temperature through the use of liquid nitrogen. Ideally this process is controlled by a computer that regulates the temperature descent and ascent in slow and controlled increments to avoid cryogenic shock to the material. Cryogenic shock can cause the material being treated to crack, shatter or incur severe internal molecular damage. Shunyata Research uses the finest computer-controlled laboratory grade equipment available. This device lowers the temperature in single degree increments. Then, there is a stabilization period before the temperature is again lowered. This continues until the temperature has reached a frosty -320 Fahrenheit. The normal cycle for a treatment is 72 hours.

During the past 7 years, Caelin Gabriel has been researching methods to enhance the cryogenic process specifically as it relates to electrical conductors. Many of these experiments involved modified atmospheric conditions involving the use of various inert gases and combinations of gases in an attempt to improve upon the effects of conventional nitrogen based cryogenic treatments.

The result is a proprietary process that creates an ideal atmospheric environment for the cryogenic process to occur. This enhanced treatment is called the Alpha Cryogenic Process. This process is applied to all Shunyata Research conductors, connectors and current carrying metals.
